Lesson 5
Unit 1
Spring is coming!
1 Read Jeremy‘s observation diary and label the plant.
In the life skills class last week, we learned about agriculture and plant biology. The teacher gave us some seeds so we could observe the growing process of a plant. I picked some pea seeds and planted them in a small pot. I watered them every day. I hope my peas grow quickly!
Here are some of my observations on the peas’ growth:
长难句分析:这是一个“Here+ be 动词+ 主语.”的倒装句,强调“这里有某物。”句中Here 为副词,置于句首引出倒装;are 是系动词;主语是名词短语some of my observations on the peas’ growth,其中on the peas’ growth 作定语修饰observations。
Date: March 3
Weather conditions:
sunny, temperature a round 18℃
Observations:
The pea seeds grew into buds. They look like the English letter “Y”. My peas are growing quickly!
Date: March 30
Weather conditions:
cloudy, temperature around 19℃
Observations:
Now, there are long, thin stems and some leaves. At the top of the stems are little flower buds! I put the pot in the yard. There, they can get some sunshine.
长难句分析:这是一个倒装句,正常语序为Little flower buds are at the top of the stems!。little flower buds作主语,系动词是are,At the top of the stems作状语。地点状语提前,句子要进行倒装,将are放在主语前。
Date: April 3
Weather conditions:
rainy, temperature around 22℃
Observations:
The pea flowers are in full bloom. Some are pink and some are purple. When the pea plants grow taller, I will give them a shelf to climb on.
I know the flowers will fade and become pea pods. Growing a plant is not easy because it takes a lot of work. Farmers grow millions of plants every year to feed us. That is an amazing thing!
